| Despite the possible influence of tannins on the nutritional value of the forages from Caatinga vegetation, there are few studies that evaluated their tannin concentration. This study was conducted to characterize condensed tannins present in the legumes species Mimosa hostilis (Jurema Preta), Mimosa caesalpinifolia (Sabiá) and Bauhinia cheilantha (Mororó), at three stages of their phenological cycle. The concentration of soluble tannin (ST), bound tannin (BT) and total tannin (TT) were determined using the butanol-HCL method; astringency was by the radial diffusion method, and the monomeric composition of purified tannins by a high-performance liquid chromatograph with delphinidin, cyanidin and pelargonidin as standards. Concentration and astringency of... |

| Apesar da possível influência do tanino sobre o valor nutritivo das forrageiras da Caatinga, poucos são os estudos que avaliam a concentração de taninos nestas plantas. O objetivo do presente estudo foi caracterizar os taninos condensados presentes nas espécies Mimosa hostilis (Jurema Preta), Mimosa caesalpinifolia (Sabiá) e Bauhinia cheilantha (Mororó), em três fases do ciclo fenológico. As concentrações de tanino solúvel (TS), tanino ligado ao resíduo (TL) e tanino total (TT) foram determinadas pelo método butanol-HCl; a adstringência foi avaliada pelo método de difusão radial e a composição de monômeros dos taninos purificados através do sistema de cromatografia líquida de alta resolução, utilizando delfinidina, cianidina e pelargonidina como padrões.

| Tempeh is a food obtained by fermentation of soybean grains by the fungus Rizophus oligosporus. It is a traditional Indonesian food that presents benefits for human health protecting against diarrhea and chronic diseases. Tempeh processing includes dehulling, cooking, inoculation, and fermentation. In this study, chemical characteristics of tempeh prepared with soybean cultivars specially developed for human consumption (BRS 216, BRS 232, BRS 257, and BRS 267) were investigated. Soybean grains and tempeh obtained from these cultivars were analyzed for oil, protein, antinutrional factors, and isoflavone content. Cultivar BRS 216 presented the highest protein content in the grains (36.81%) and in tempeh (51.99%). On average, the protein content in tempeh... |

| Sapucaia (Lecythis pisonis Camb.) raw nuts collected from Brazil were analyzed to determine the proximate composition, amino acid profile of protein fractions, in vitro protein digestibility and antinutritional factors in order to evaluate their potential as a protein alimentary complement. The nuts contained adequate amounts of essential amino acids, fatty acids and minerals. In the present study, no hemagglutinating or inhibitory activities were observed in any of the samples investigated, indicating low or non-detectable levels of proteinase inhibitors or lectins in the samples. In vitro digestibility of in natura and heated nut globulins by mammalian digestive proteinases was carried out using trypsin + chymotrypsin + peptidase, with resulting mean... |

| Diferenças em níveis de inibidor de tripsina Kunitz e ácido fítico foram determinadas para cultivares de soja convencionais e transgênicas cultivadas em Londrina e Ponta Grossa, Sul do Brasil. Os níveis de inibidor de tripsina na região de Londrina e Ponta Grossa para variedades convencionais variaram de 14,56 mg g-1 (BRS 267) a 20,40 mg g-1 (BRS 261) e de 13,51 mg g-1 (BRS 232) a 19,65 mg g-1 (BRS 268), respectivamente, enquanto para as variedades transgênicas foram encontrados valores de 14,16 mg g-1 (BRS 242 RR) a 18,21 mg g-1 (BRS 255 RR) para Londrina e 13,68 mg g-1 (BRS 244 RR) a 18,73 mg g-1 (BRS 256 RR) para Ponta Grossa. A média de teor de ácido fítico em variedades convencionais e transgênicas de Londrina teve variação de 2,05 a 1,78 mg g-1,... |

| Gluten-free foods are a growing trend in the domestic and international markets, contributing to health and wellness, especially the celiac public. The objective of this study was to create a new option of gluten-free food by replacing wheat flour by rice grit flour, cornstarch, and extruded split bean flour, and to aggregate value to low cost industrial byproducts. A new food product was developed and its components analyzed for their nutritional characteristics and changes during baking. The baked cakes can be a source of protein, had a good starch and protein digestibility, and low antinutritional factors, notably tannins. Incorporation of an extruded bean flour in a gluten-free cake mix improves protein digestibility, total dietary fiber, and raises... |

| Due to the importance of studies on yacon related to health, its in natura pulp, in natura peel, pulp flour, and peel flour were chemically analyzed in terms of its centesimal composition, specific minerals, total dietary fiber and fractions, pH, total soluble solids, total titratable acidity, tannins, oxalic acid, and nitrate. The polyphenoloxidase and peroxidase enzymatic activities were evaluated for in natura pulp and peel only. Yacon pulp and peel flour presented average yield of 7.94% and 10.86%, respectively. The in natura pulp presented a higher moisture and carboydrate content and lower lipid, protein, total dietary fiber, and ash than those of the peel flour. The same pattern was observed for pulp flour when compared to peel flour. The highest... |

| This study was carried out on a low-productive Brachiaria brizantha cv. Marandu pasture, mixed with Arachis pintoi cv. Belmonte (forage peanut), established 13 years ago in a Red-Yellow Latosol in Acre State, western Brazilian Amazon. The purpose was to evaluate the response of this pasture to different fertilizer combinations, aiming at identifying the nutritional factors responsible for the fall of pasture carrying capacity and for the reduced vigor of forage peanut. It was used a randomized complete block design, with three replications and 12 combinations of nitrogen, phosphorus, potassium, lime, sulfur, and micronutrients (100 kg/ha of N, P2O5 and K2O; 300 kg/ha of dolomitic lime; 30 kg/ha of sulfur and FTE BR-10). Fertilizers were broadcast in 5 ×... |
